Cascade Parameter becomes invalid

A cascade parameters contains two parameters: p1 and p2.
And I use jsapi to access reports deployed in iserver express.

Usually, it works well. But sometimes it is broken for some unknown reasons.
And is will not recover until i redeployed it.

When it is broken, the selection of p1 will not bring a ajax request for p2. And the dropdown list of p2 displays a value, which is the default value of p2 setted when designing. In fact it should be a Label Value list base on the the value of p1 by a ajax request.

Anyone can help. Thanks.

Can you post the test page you are using?

Hi Jason,

thanks for your reply.

what does the test page mean, .jsp or .rptdesign?
i do not think it is useful to study .jsp file, because most of time it works well and once it is broken, all accesses to the report(.rptdesion) will face the invalid parameters even by iportal.

i guess it may be because the iserver cache which stored the invalid object.
i said that it will be restored by redeploying that .rptdesign file. i guess iserver will re-create the report object which replace the invalid one when redeploying.

any suggestions?

Thanks.
